Unstaked EOS become unavailable when unstaking OTHER EOS

[dscotese]

I unstaked 220 EOS a few months ago. Today, I was going to unstake some more and spend some of the 220. I have already signed and broadcast the transaction to unstake what I wanted to unstake, and now EOSimple claims that the 220 I had unstaked a long time ago is still locked up.

I don't think this is by design. I think it's a coding error. Unstaked EOS should remain unstaked and available to be used regardless of what the owner does with staked EOS.

Now I have to wait three days to use the EOS that I unstaked a few months ago. :-(

Now that I understand what happened, here is a solution I think would work, in pseudo-code:

//Unstaking = amount of EOS user wants to unstake, if they are unstaking.
//UserPref = user-specified ratio of CPU:NET (ideal is 75:25, default was 50:50)
if( Unstaking ) {
    // If UserPref is 50/50, ignore it.
    if( UserPref = 1 ) UserPref = 3;
    // Aim for UserPref
    TotalStake = CPUStake+NETStake;
    NewTotalStake = TotalStake - Unstaking;
    targCPUStake = (UserPref * NewTotalStake) / (UserPref + 1);
    targNETState = NewTotalStake - targCPUStake;
    UnDelCPU = CPUStake - targCPUStake;
    UnDelNET = NETStake - targNETStake;
    // If we can't hit the target, offer options.
    if( CPUStake < targCPUStake || NETStake < targNETStake ) {
        if(Holdings > TotalStaked) { // Offer the user the option to stake unstaked EOS.
            // The existing code does this after displaying a message, so
            // I'm not going to recalculate everything, but I propose that after
            // it determines the new values, (UnDelNET and UnDelCPU), it offer
            // that option plus the following:
            if( UnDelCPU >= UnStaking ) {
                OnlyUnstake = "you will just unstake "+UnStaking+" EOS which are currently delegated/
                    to CPU usage."
            } elseif( UnDelNET >= UnStaking ) {
                OnlyUnstake = "you will just unstake "+UnStaking+" EOS which are currently delegated/
                    to NET usage."
            } else { // Unstake using the larger one first and the leftover from the other one.
                udLarger = (UnDelNET > UnDelCPU ? UnDelNET : UnDelCPU);
                udSmaller = UnStaking - udLarger;
                lgType = (udLarger==UnDelNET ? "NET" : "CPU");
                smType = (udLarger==UnDelNET ? "CPU" : "NET");
                OnlyUnstake = "you will lower your "+lgType+" delegation by "+udLarger+" EOS and/
                    your "+smType+" delegation by "+udSmaller+" EOS.";
            offerToStake = "When you unstake these coins, you can use coins you've already unstaked/
                to approach the ideal ratio of CPU stake to NET stake (75:25).  This will relock those coins/
                for three days.  If you choose not to do this, "+OnlyUnstake;
